S-97832A355 5-40 Shoulder Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with 18-8 Stainless Steel construction, ideal for harsh industrial environments.
• High tensile and shear strength (70,000 psi tensile, 35,000 psi min shear) ensures reliable performance under heavy loads.
• Precise Class 3A thread fit guarantees secure, vibration-resistant fastening in critical assemblies.
• Knurled socket head with hex drive provides superior grip and prevents tool slippage during installation.
• 1" shoulder length with tight tolerances enables accurate component alignment and spacing.
• Full compliance with RoHS 3 and REACH meets stringent environmental and safety regulations.
• Coarse UNC threads allow for quick assembly and disassembly in maintenance-heavy applications.

Professional Applications & Engineering Value

This 5-40 UNC shoulder screw is engineered to address common challenges in precision machinery, automation systems, and assembly jigs. The 18-8 Stainless Steel material offers excellent resistance to rust and chemical exposure, while the Rockwell B55 hardness ensures durability against wear. The 1" shoulder length with controlled tolerances provides a stable pivot or spacer, reducing misalignment and component drift. The knurled socket head enhances torque transmission, minimizing cam-out risks in high-vibration environments like robotics or conveyor systems. Ideal for applications requiring repeatable accuracy and long-term reliability.
